Inconsistent Guy, interested or just a nice guy?

A guy I started talking to about a month ago seems really interested, really interested what I do on the weekends, I even met his parents at small family barbecue, however he makes almost no initiative to make any plans. Is he interested or is he just nice/friendly. What do you think the issue is?

Updates:

when i went out to dinner with him, he told me he is free almost any day and isn't doing much and we should hang out again. so a few days later i suggested we make plans and he said absolutely... but we still have no plans to speak of...
